To load a previous design, enter its 6-letter taghelpWe store all the designs of our users in our database so they can be retrieved later if needed.
Each design is identified by a unique 6-letter (uppercase) tag.
If you have written down such a tag from a previous session or if someone has shared with you the tag of its design, enter it to reload that design.
The tag of your design will be displayed on the next page, after generation of the 3D data.
If cookies are enabled in your browser, the field is already filled with the tag of your last design. So just click 'load' if you want to retrieve it.
It you load a previous design and modify it, the modified design will automatically be given a new tag.

Stud adjustment
helpDue to the characteristics of your 3D printer, the printed stud of the brick may be a little bit too small or too large, preventing a good assembly with standard LEGO™ bricks.
If you need a tighter adjustment (i.e a stud a little bigger), move the cursor to the right. Moving the cursor to the left will give you a looser adjustment (i.e a stud a little smaller).
First try to print a small test brick with the cursor in the central position (nominal size) and then adjust as needed.L5L4L3L2L1NT1T2T3T4T5

Cavity adjustment
helpDue to the characteristics of your 3D printer, the bottom cavity of the printed brick may be a little bit too small or too large, preventing a good assembly with standard LEGO™ bricks.
If you need a tighter adjustment (i.e a cavity a little smaller), move the cursor to the right. Moving the cursor to the left will give you a looser adjustment (i.e a cavity a little bigger).

Body adjustment
helpDue to the characteristics of your 3D printer, the size of the body (width/depth) of the printed brick may be a little bit too small or too large, preventing a good assembly with standard LEGO™ bricks.
If you need a tighter adjustment (i.e a body a little bigger), move the cursor to the right. Moving the cursor to the left will give you a looser adjustment (i.e a body a little smaller).

Height adjustment
helpDue to the characteristics of your 3D printer, the height of the brick may be a little bit too small or too large, preventing a good assembly with standard LEGO™ bricks.
If you need a tighter adjustment (i.e an height a little bigger), move the cursor to the right. Moving the cursor to the left will give you a looser adjustment (i.e an height a little smaller).

Reinforcement
helpThis apply to full height bricks only. In these bricks the length of the cylinders present in the bottom cavity can make them less solid in 3D printed pieces than on original injected LEGO™ parts.
Type 1 will add small reinforcement walls around the bottom cylinders. Type 2 will fill some more space of the bottom cavity so the cylinders are shorter, while keeping the compatibility will standard bricks.
The generation time will increase when selecting type 1, as well as the printing time as a lot of small details are added. Type 2 will probably print much faster as it will benefit of the infill algorithms of the slicer program of your printer.
